Maryland State Police did not immediately identify the woman pending notification of her family. Sgt. Michael Dornberger said the woman was driving a Toyota Camry north on Route 301 near Pointer Ridge Drive around 2:30 p.m. when the accident occurred.

Dornberger said the cause of the crash has not yet been determined. He said investigators are looking into the possibility that the woman suffered from a medical emergency that caused her to lose control of the car.
